Subject: [obol] migrating Swainson's Thrushes
Others have noted the passage of Swainson's Thrushes in the early morning hours. But an alternative to enjoying this wonderful event is to listen to them in the evening, just before they set off on their nocturnal journeys. To experience it to the full, go to a heavily wooded area, as far from city noise as possible, before dusk begins to settle. About the time the light begins to fade (last night it occurred at 8 p.m.) the birds in the woods begin giving their "whit" call to one another. This usually goes on for five minutes or so, with the voices of many birds answering one another from all quarters. Then, just before darkness starts to overwhelm the light, there will come the "heep" call of an airborne bird, and in an instant, the "whit" call will cease as the entire body of thrushes rise en masse into the sky to continue their nightly sojourn.
